The 27-year-old Rosales, who carded a five-under-67 on opening day, came through with seven birdies this time to score a 65 and move to within two shots off solo leader Young Kim of South Korea and a stroke behind Annika Sorenstam for solo third.

Rosales had birdies on the second, third, fifth and sixth holes in the front nine and then came in with another string of birdies on the 14th, 16th and 17th.

Both Kim and Sorenstam carded 67s. Sorenstam, tied with Laura Davies for the LPGA Tour record for consecutive victories in a tournament with four, had six birdies and a bogey in the second round on the Seta course. Davies won the Standard Register Ping from 1994-97.

The Swedish star, a nine-stroke winner in each of the last two seasons, is 87 under in her last 14 rounds in the tournament. She has eight LPGA Tour victories this year and also won a European tour event in Sweden.

Kim, who opened with a 63 to take a one-stroke lead over Sorenstam into the round, had eight birdies and three bogeys in her 67. The 25-year-old South Korean player is winless in three full seasons on the LPGA Tour.

Australia’s Karrie Webb (66) and South Korea’s Jeong Jang (67) followed at 11 under. Sweden’s Sophie Gustafson (67) was 10 under along with Japan’s Shiho Ohyama (69).
